Mechanism
Agonist at the ghrelin receptor (GHS-R1a) on the pituitary and hypothalamus, amplifying GH pulse amplitude, especially when combined with a GHRH analog.
Half-life
~2 hours
Routes
Subcutaneous injection
Legal / access
Not approved for general anti-aging or performance use; research-chemical distribution is common.
Key risks
- Mild flushing
- Headache
- Injection-site reaction
- Rare water retention
Common claims
